Polarization intensity maps at 100 and 143 GHz obtained applying SRoll1 and SRoll2 to a set of simulated timelines. The input sky has been subtracted after the map projection. The simulated timelines contain dipole, sky signal, systematic effects and electronic noise only. First row: maps obtained running SRoll1 with only one gain for the entire mission, middle row: SRoll1 with 128 gain steps, as used in the Planck 2018 legacy release, and bottom row: SRoll2 results.
